Efficient but a bit noisy 1

The unit I liked the sense that it heats very well, there is no odor, the remote is super convenient when you are in bed and was too lazy to get up. Able to adjust the temperature is also very practical, you can choose the temperature you want for your play and then when it is reached the heater stops. Finally, the function used to turn on or off by itself after some time must be a multiple of half an hour, also works well.
The only downsides are: 1. noise, because in the beginning it was hard to sleep with, but now I feel better, it was a little used; and 2. sometimes it stops because it has reached the desired temperature, but then after that no longer lights when the temperature falls below which we had programmed. I have not yet managed to solve this problem, but apparently it got better after I cleaned the filter device (there were dusty ..).
